To the surprise of many, Dragon Ball Super has confirmed that Goku simply awakening and mastering Ultra Instinct isn’t the final goal for Goku. In fact, Whis has revealed in the latest Dragon Ball Super manga chapter that Whis, the other angels and the Grand Priest are all still significantly stronger than Goku.
Goku has only tapped into Ultra Instinct and just like the Super Saiyan transformations, there are other levels of that power and fighters can increase the potential of the transformation. The level where Goku is now is just like his mastery of the Super Saiyan form back when he first awakened it in Dragon Ball Z against Frieza.
That means that there is still a long way to go for Goku. However, we are unsure if we will see anything like Ultra Instinct 2 or 3, which some fans are hoping for. I’m sure though that we will see more. Maybe Ultra Instinct while in the state of Super Saiyan 3 is possible but for now, that would contradict the way Ultra Instinct is accessed.
I guess we will have to wait and see what Dragon Ball Super has installed for Goku. In the meantime, the Oracle Fish revealed during a slumber that the strongest in Universe 7 will soon be born. Is this Goku? Is it Vegeta while he learns off Beerus? Could it be Broly? Is it Gohan even? It could also be the new villain in Granola? All are possible options but a whole new character is also a possibility as well.
